Sisters of Saint Lila's Academy

Set beside the other Marukane performers, the three of them read as children. They match one another in height and build, and telling them apart means going by hairstyle, since only slight differences in their faces and hair colors separate them otherwise. Luminescent blushes are a near-constant feature.

Their clothing matches too, most often the sailor fuku of their school worn with a beret carrying a flower on the right side.

Their profile notes that despite how they look and act, all three are middle schoolers, putting them close in age to Pop, Miu, and Yu.

Youth makes them innocent and candid to a fault. Concepts and arguments regularly go over their heads, and they think nothing of asking the adults around them for an explanation.

All three adore Captain Celebrity, and any occasion that puts their idol beside them sends them into delight.

During the Osaka Incident Arc the trio performed at the second Naruhata Festival inside the Marukane Department Store, closing out the morning with "Can't Help Loving You". On the break they ran into Miu of FeatherHATS in the Green Room, who warned them against treating Narufest as a talent show, since Heroes might be watching, and told them to take their stagecraft seriously. They agreed enthusiastically.

Miu also promised a hero as special guest, then learned from Pop Step that Captain Celebrity was stuck filming a commercial and could not come. Cornered by one of the girls asking which hero it would be, Miu improvised that the identity was a surprise, which only wound them up further. Koichi wandered into the Green Room at that exact moment and was presented on stage as the guest, where his performance underwhelmed. Yu apologized for it; the girls said they found the young man's efforts funny but still wanted the Pro Hero they had been promised, to Yu's dismay.

Minutes later Batto Yobayakawa, a villain Koichi had beaten previously, snatched him off the stage and flew off to settle the score. Captain Celebrity arrived, punched the villain down, and saved him, and the girls could not contain themselves at meeting a real Pro Hero. He is good with kids and plays with them often, and their fondness runs both ways: when the Bomber's self-detonation threatened them, he shielded the three with his aerodynamic barrier and took several wounds himself by lowering his own protection to do it.
